  • Harmonic Highlights:

    • Prevalent b5b9 alterations on dominant chords (Bb7, Ab7, Db7) create significant chromatic tension.
    • The Eb7sus chord introduces a dominant quality on the tonic, potentially delaying resolution or setting up secondary dominant functions.
    • A clear ii-V-I progression (Abm7-Db7b5b9-Gbmaj7) leads to Gb major, the relative major of Eb minor, offering harmonic relief.
  • Improvisation Focus: Altered Scale (Super Locrian) to effectively outline the numerous b5b9 dominant chords.

  • Difficulty Rating: 4 (Advanced Intermediate) - The consistent use of altered dominants and temporary modulations demands sophisticated harmonic understanding and scale application.
